Serial No. 179,684.

My invention relates to improvements in filling mechanisms of the type which are adapted to dispose measured amounts of liquid, such as syrup, in bottles, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a filling mechanism in which the capacity of the measuring means may be varied to the slightest fraction of an ounce.

A further object `of invention is to provide a device of the type described in which the members of the measuring means may be moved simultaneously for varying the capacit` of the measuring cup.

A further obj ect of my invention is to provide a device of the type described by means of which the capacity of the measuring cup may be varied at a relatively great speed.

`A further object of my invention is to pro vide a device of the type described by means of which desired quantitiesof the liquid may be disposed in each bottle, irrespective of the temperature effect upon the liquid or the` density of the liquid used;

Other objects and advantages will appear' in the following specification, andthe novel features of the invention will be particularl pointed out in the appended claims. v

My invention is illustrated in the accompanying drawings, forming part of this application, in whic y i y Figure 1 is aside sectional view of my device, portions thereof beingnshown in elevation, A y, y y,

Figure 2 is a plan view of my device, and Figure 3 is asection along the line 3-3 of Figure 1.

In carrying out my invention, I provide a liquid tank l having one or more openings 2 in the bottom 3 thereof. guide or support rod 4; is slidably disposed in a bushing 5 which extends througlithebottom 3 of the` tank'l. A bell 6 for "receiving the neck of a bottle which i'rsfindicated at y `7 is rigidly mounted upon the lower end of the guide rod 4i. A compression spring 8 `is disposed concentric with the guide rod 4 and bears at one end upon the bell portion 6 andat the kother end upon the bushing 5. Asupport 9 is se cured to the upper end of the guide rod 4 by means of a nut 10.

A measuring cup which is composed of a cylindrical body portion 11 and a bottom portion 12 is disposed in the tank 1. The measuring cup is so constructed that the cylindrical body portion 11 may be moved with respect to the bottom portion 12 and still prevent a liquid from passing from the cup between tlie body portion 11 and the bottom portion 12. A bushing 13 is provided for the bottom portion 12. The inner wall of the bottom portion 12 tapers inwardly and downwardly to a point adjacent the bushing 13. The tank 1 is provided with a liquid 14 which maintains a level shown in Figure 1, by means not shown. A liquid valve tube 15 extends through the bell 6, through the opening 2, and through the bushing 13 to a point above the level of the liquid 14.

The body portion 11 is provided with a hollow sleeve or tube 16 which issecured at one end thereto. The other end of the sleeve 16 extends upwardly and is provided with an arm 17 'which extends outwardly at right angles therefrom. A threaded shank 18 is secured to the arm 17 and extends upwardly therefrom. A drive gear 1.9 extends through the support 9 and is provided with an internally threaded portion 20 which is adapted to receive the threaded shank 18. A relatively smallgear 21 is rigidly mounted upon the drive gear 19.

The bottom portion 12 is provided with an annular recess 22 whichis adapted "to receive a fork 23. An adjusting rod 211 is secured at one end to the fork 23 and extends upwardly through the sleeve 16 and is adapted to be moved with respect to the sleeve. The upper end of the rod 24 is provided with threads 25. A driven gear .26 extends through an opening in the support 9 and is in mesh with the drive gear 19. The driven gear 26 is provided with an internally threaded portion 27 which is adapted to receive the threaded portion 25 of the `adjusting rod 241. A reduced portion 28 is provided on the driven gear 26 for receiving a relatively large indicating gear 29. `.The indicating gear 29 is in mesh. with the relatively small gear 21 and is held ad'acent the periphery of the gear 29.

ear-retaining flanges 34 and 35"are provided with semi-circular portions .-36 ,and :37 which are receivable in annular grooves 38 and 39 .of .the Zgears 26 and 19 respectively. The retaining flanges 34 andB' are removably secnredto the support 9 by screws ,40'and 411 respectively. i l

A drip .check valve 4:2is adj ustably secured to the ysupport 9 by .a bar/13 and a screw 44. The drip check ,12 is disposed in alignment ywith the vliquid valve tube and'ada-ptedto engage Vwith the upper .end go the liquid valve tube vwhen the drip check isin its lowermost position.

From the'foregoing .description ot the various 4parts of the device, theoperation thereofvma-y .be-readily understood. As stated heretofore` the liquid 14 maintains approximately .the level shown in Fig-ure 1,-irrespective of the speed atwhich 'the liquid .passes from the tank.

The .capacity .of themeasu-r-ing .cup is from one to four ounces. However. vthe measuring cup may beso adjusted to'hold a. fraction less than .one ounce .orafraction more .than four ounces,if so' desired.

Let ius (assume that the operator wishes -to place four ounces of the liquid 1i into the bottle The measuring cup, vas shown Figures 1 and 2. is set v.to receive just four ounces of the liquid. VAsti-ie bottle 7 is moved upwardly, by means not shown. .the bottle engages AWi-th'the bell 6, thus raisin.'` :the bell,

' the .guiderod LLathe supporti).v and the meas.- Vuring .cup upwardly to a point where the nnper extremity of the measuringcup will be positioned above the l'level ,oit the vliquid 14.

vDuri-ng this upward movementofvthe mea uring cup, the 'full capacity' which is four ounces of the liquid will bel received vin the measuringeup. Whenthe measuring cup h as reached its uppermost position, the drip check/i2 will have 'been raised from `the liquid valve tube 115 and the .upper extremity 0f fh@ liquid relive 'tube will lief-adjacent .the 10u61 pertinenti@ nrerirq Surfers@ of the bei? @0.1.1.1 Perrier Thi 1` @We thelliiiuid which I has ,been retained iin the measuring @up .t0 Vfion'A .downwardly f through. vthe liquid valve tube 15mn) bottle The tapering surffllleehefem einer 12nd@ thelliqrd yI ir und #le tube .1.5. sa@ retraits all the liquid in the measuring cup to pass therefrom in a given time.

As the bottle 7 moves downwardly, the measuring cup is also moved downwardly by the force of the compression spring 8, and the drip check 42 engages with ythe upper end of the liquid valve tube 15 for preventing any liquid which should remain in the tube trom passing therefrom until another bottle is brought into alignment with the tube. T he drip check 42 is essential when the device is lused in a low surrounding temperature or with a heavy liquid for holding all the liquid over the predetermined amount which is received in the measuring cup.

In filling machines of this type, a `certain length of time is given for the .passing of zthc liquid from lthe measuring cup into-thc bottle. This time remains the same, irrespective ot the. surrounding i'eii'rpcifatiilc for the speciic gravity ,of the syrup. As for instance, u liquid, .such as a syrup, will flow at a slower rate of speed during a. relatively low surrounding temperature than when the surrounding tcnnrerature is relatively high. Some syrups or liquids owingto their density require more time to How from the .measuring cup into the bottle than do others. To allow for the slowness of the flow of liquid during a relatively low temperature or with the use of a relatively licavy'syrup, `the body portion 1'1 -and the bottom portion lf2 may be moved .simultaneously with .respect to each other.

The lsimultaneous movement of the bottom portion 12 and the body portion 11 with respect yto each other is effected ,by rotating the gear 1 9. Let us assume that the operator wishes .to' reduce the `capacity of the measuring cup to three ounces. By rotating the gear 1-9 in a counter-clockwise direction, see Fig ure 2, the shank 18 will be moved downwardly, 4thus moving the sleeve 16 with respect to the adjusting rod v24 and moving the body portion 11 with respect to the bottom portion 12. During the rotation of the gear 19 in a counter-clockwise direction, lthe gear 26 will be rotated in a clockwise direction, thus cansing the adjusting rod 124 to move upwardly within the threaded opening 27. During the upward movement of the adjusting rod 24, the bottoni portion 1-2 together -with the fork 23 will be moved upwardly with respect to the body portion 11. In ythis n ianner.l the body portion 1 1 and the bottom portion 12 lare moved simultaneously with respect to cach other. To change ,the capacity of the measuring cup from four ounces-to three ounces. it is necessary to rotate the gear 19 two reyolutions. 'During the revolving ,of the gear 19, the gear 21'v11fr0tnt@ the indicating .een l29 until the line bearing ,the numeral 3 there upon is in registration with `the indicating 139m? 3,3- Qozltlnlll :IOHQH Of .the drive ser? .19 and the .relatively small gear 21 will lill) CSi decrease the capacity ofthe measuring cup in accordance with the markings upon the indicating gear 29 as they align with the indieating point 33. It is obvious that with the simultaneous movement of the body portion 1l with respect to the bottom portion 12, the capacity of the measuring cup may be varied to the desired capacity in a short length of time.
